A method of transferring messages between a plurality of processes that are communicating with a data storage system, wherein the plurality of processes access the data storage system by using I/O services. the method includes the steps of configuring the data storage system to provide a shared data storage area for the plurality of processes, wherein each of the processes is permitted to access the shared data storage region; when a sending process sends a new message that is intended for a recipient process, sending that new message to the data storage system; storing that new message in the shared data storage region; in response to an action initiated by the intended recipient process, retrieving that new message from the shared data storage region; and further in response to the action initiated by the intended recipient process, sending the retrieved message to the intended recipient process, wherein the sending and intended recipient processes are among the plurality of processes.
